SLE10 Expert Series Slot Sensor Overview

The SLE10 Series Slot Sensor (sometimes called a “Fork Sensor”)
comprises an opposed-mode emitter and its receiver inside a single
convenient housing. Opposed-mode sensing is very reliable, and the
single self-contained housing provides easy installation, with no
sensor alignment required. In addition, the molded-in arrow on the
emitter portion of the housing and the slotted design on the receiver
portion of the housing show at a glance the position of the beam,
simplifying installation placement.

Expert series sensors feature easy-to-use push-button programming,
performed in TEACH mode. TEACH-mode programming may be
performed using either the push button, or remotely, using a remote
switch or process controller. The programming determines whether
the sensor outputs will conduct in light or dark conditions, and defines
the light and dark conditions for the sensor in each application. The
remote switch also may be used to disable the programming push
button for security.

The Dynamic TEACH option provides a means for teaching a series of
conditions; the SLE10 monitors the sensing events and automatically
sets the threshold between light and dark conditions.

Using the SLE10 Expert Series Slot Sensor

RUN Mode

Normal operation of the SLE10 Expert is called RUN mode. The two LED indicators
(bi-color Green/Red and Yellow) operate as follows in RUN Mode:

Green (RUN Mode): ON steady whenever power is applied

Flashes as received light level approaches the switching threshold
(stability indicator. The stability indicator signals when
maintenance or reprogramming is needed during RUN mode.)

Yellow (Output): ON when the outputs are energized (conducting)

OFF when the outputs are de-energized (not conducting)

If contrast is marginal, the bi-color indicator will flash green (to indicate instability).
Reprogramming the sensor, or cleaning the sensor lenses may solve a problem with
stability.

TEACH Mode

Programming of the SLE10 Expert – setting the sensitivity and selecting output ON and
OFF conditions – is performed in TEACH Mode. The SLE10 provides two methods for
programming: Static TEACH and Dynamic TEACH. Static TEACH is used in all
programming situations to set up the sensor’s output ON and output OFF conditions.
Sensitivity is then set using either the Static method described below or the Dynamic
method on page 4.

Both Static TEACH and Dynamic TEACH may be performed using either the sensor’s
TEACH push button or the Remote TEACH line (see page 6).

Static TEACH

Determining the Output ON and OFF Conditions

The two sensing conditions may be presented in either order. The condition presented
first is the condition for which the outputs will energize (the “Output ON” target).

Setting Sensitivity

Sensitivity is automatically set (and optimized) when teaching the sensor the ON and
OFF conditions. When the push button is clicked, the sensor samples each sensing
condition and registers it into memory. After the second sensing condition is
registered, the SLE10 Expert automatically sets the sensitivity to the optimum value
for the application, and then returns to RUN mode.

The two LED indicators (bi-color Green/Red and Yellow) operate as follows in
TEACH Mode:

Red (TEACH Mode): Lights when the sensor “sees” its modulated light source;

pulse rate is proportional to the received light signal strength
during TEACH programming

Yellow (Output): ON to indicate TEACH output ON condition

OFF to indicate TEACH output OFF condition

The Signal Strength indicator is Banner’s exclusive AID™(Alignment Indicating
Device). Its pulse rate increases as the received light signal strength increases (during
programming). This feature simplifies accurate alignment during TEACH mode, and
gives a relative indication of sensing contrast between the light and dark conditions.

A Note About the “Clicks”: Clicks are meant to be pressed firmly, then quickly
released. Indicators go ON or OFF after a brief delay; do not wait until LEDs change
status before releasing push button. (If push button is pressed for 2 seconds or
longer, sensor will automatically return to RUN mode.)

Dynamic TEACH

Dynamic TEACH is a method of setting the sensor’s sensitivity while the object to be
sensed is in motion. Typical applications are label sensing and small parts detection. In
a label application, web flutter may change the amount of light passing through the
label and its backing material. Dynamic TEACH will sense this variation and adjust the
sensitivity to account for it.

In a small parts detection application, alignment of the object to the sensor’s effective
beam may make Static TEACH difficult. In this case, Dynamic TEACH will allow you to
pass individual or multiple parts through the beam; the sensor then will detect them and
set the sensitivity automatically.

Determining the Output ON and OFF Conditions

Dynamic TEACH is used for optimizing the sensor’s sensitivity and will not configure the
output ON and OFF conditions. A Static TEACH must be used first to change the output
ON and OFF conditions, if needed. If the outputs are configured properly for your
installation, Dynamic TEACH may be performed as needed without reverting back to
Static TEACH.

Setting Sensitivity

Sensitivity is automatically set and optimized when the sensor is taught dynamically.
When the push button is depressed and held, the sensor continues to sample events
and registers them into memory. Upon release of the button, the sensor chooses the
optimum setting for the application and then returns to RUN mode.

Dynamic Sampling Rate

When using Dynamic TEACH to sample an application for programming, it is important
to consider the speed of the object being sensed. The sensor’s sampling rate during this
set-up process is much slower than its response time in RUN mode. Once sampling is
complete and the sensor returns to RUN mode, sensor response time returns to its
original value.

Use the following formula to calculate the target object speed for Dynamic TEACH
sampling:

Max. speed of object =

as it passes the sensor

For example, for an object 0.125" wide: Or for an object 2 mm wide:

(0.125" - 0.04") (2 - 1 mm)

Max. object speed = = 9.4" /second Max. object speed = = 111 mm/second

0.009 seconds 0.009 seconds

*NOTE: The Dynamic Sampling Rate for high-speed models (“Y” model suffix) is

8 milliseconds (0.008 seconds)

†

NOTE: The sensor will return to RUN mode if the first TEACH condition is not registered within 90 seconds. Dynamic TEACH mode may be

cancelled by waiting 90 seconds or by cycling sensor power.

Remote Programming

The gray wire of the SLE10 Expert may be connected to a remote
switch or process controller to disable or enable the push button
(four-pulse) or to program the sensor (single-pulse) through
TEACH mode. Remote programming may be done for both the
Static and Dynamic TEACH procedures.

A remote programming switch is connected between the gray wire
and dc common (see hookup diagrams on page 9). The switch may
be either a normally-open contact, or an open-collector NPN
transistor with its emitter connected to dc common.

Programming is accomplished using a specified sequence of
input pulses. The duration of each pulse is defined as:

0.04 seconds<T<0.8 seconds.
The required spacing between adjacent pulses in a sequence

(a “four-pulse”) is also: 0.04<T<0.8 seconds. The timing diagrams
(Figure 3, right) illustrate the input requirements.

Locking Out (Disabling) the Push Button

When remote programming is used exclusively, it may be beneficial to disable the
push button on the SLE10 Expert to increase the security of the settings. The push
button can be enabled and/or disabled via the remote line only. If the push button is
disabled, TEACH mode cannot be accessed from the push button.

Pulse the Remote TEACH line 4 times (four-pulse) to enable or disable the push
button (see timing diagram, Figure 3).

Static TEACH Programming Using the Remote TEACH Line

To pulse the TEACH line, momentarily connect the remote wire to dc common (no
press-and-hold procedure is required to enter TEACH mode). This is the equivalent of
a “click” when using the sensor TEACH push button.

1. Position the “Output ON” condition and pulse the Remote TEACH line once. The
bi-color (green/red) indicator begins to flash red or turn OFF (the AID

™

function is
indicating signal strength) and the yellow Output indicator will flash briefly and then
go OFF.

2. Position the “Output OFF” condition and pulse the Remote TEACH line again. The
green indicator will turn ON and the sensor will return to RUN mode with the new
settings, if the contrast is adequate. If the contrast is not adequate, the yellow
indicator will turn ON and the red AID indicator will remain active, indicating that
the sensor is waiting for the first TEACH condition to be retaught. (RUN mode
begins a few seconds after the end of TEACH mode.)

NOTE: To exit Static TEACH without updating, hold the Remote TEACH line low

(longer than 2 seconds) until the green indicator goes ON, before teaching the

second target.

Dynamic TEACH Programming Using the Remote TEACH Line

To pulse the TEACH line, momentarily connect the Remote (gray) wire to dc common; no
press-and-hold procedure is required to enter TEACH mode. (This is the equivalent of a
“click” when using the sensor TEACH push button.)

1. Using the Static TEACH procedure, set up the application’s Output ON and OFF
conditions. (This step is not necessary if the Output ON and OFF conditions already
are configured properly for your application.)

2. Double-pulse the Remote TEACH line (see Figure 3). The sensor is now ready for
Dynamic TEACH. The bi-color (green/red) indicator will be ON solid red and the
yellow indicator will flash.

3. Hold the Remote line low. Sample sensing events while continuing to hold the
Remote line low.

4. Release the Remote line when event sampling is complete. The green indicator will
turn ON and the sensor will return to RUN mode with the new settings, if the
contrast is adequate.

If the contrast is not adequate, the red indicator will flash at a rate proportional to the
received light signal strength and the yellow indicator will be ON solid, indicating that the
sensor needs to be retaught. In this case, return to step 2.

NOTE: To exit Dynamic TEACH without updating, wait 90 seconds or cycle sensor power.

Troubleshooting

The SLE10 Expert’s Power LED may begin to alternate flashing red/green; this
indicates a microprocessor memory error. If it occurs, try reteaching the sensor, or
try cycling power ON and OFF, then reteaching the sensor. If this does not solve the
problem, or if it occurs frequently, replace the sensor.
